Sir Alex Ferguson wants to make United the undisputed all-time kings of England before walking away from football. Fergie knows his incredible career cannot go on forever and is desperate to see his side move clear of Liverpool with a record 19 league titles. He is chasing an unprecedented fourth successive Premier League crown this season and believes United are ready to see off the challenges of title rivals, Chelsea and Arsenal. "The record we are chasing is four titles in a row," he said. "That would be fantastic. It would be the 19th title - the most in the league. It doesn't matter who you beat for that record - and we've got a chance." Fergie would also love a third Champions League after last year's painful defeat to Barcelona in the final in Rome. The United boss refused to set a date for his retirement, but at the age of 68 has increasingly hinted that it will be sooner rather than later. After winning the Carling Cup earlier this month he said he might be "too old" to win many more trophies. And yesterday he suggested that a league and European Cup double would be the perfect way to bow out. "It would be a nice way for all of us to go out, whichever year it may be," he said. Fergie is sure to keep everyone guessing as to when he will call an end to his glorious career - but he faces a race against time to add to United's trophy count if he sticks to his hint of staying two more years. And with the champions two points clear of Chelsea at the top of the table, but having played a game more, he believes his side have the bottle to make it a quadruple of titles. Chances Last Saturday against Wolves was the best indicator of our chances, he said. We've had these kind of games over the years where players are prepared to battle against a very determined team, on a lively surface. It was not an easy game, but they were not going to lose. That is a good indication for me. I enjoyed it. It's not the kind of game you like to watch because it was such a battle, but I enjoyed the fact the players stood up to it and wanted to win because of the importance of the game. That's the way it's going to be to the end of the season. Through the years when we've had these kind of results, they've always been really emphatic and influential for us. United also have the massive boost of Rio Ferdinand and Nemanja Vidic returning to fitness and form at a crucial stage of the season. Fergie's first-choice central defensive pairing were imperious in the 4-0 Champions League demolition of AC Milan on Wednesday, which bodes well for United's challenge on two fronts. When I see the two of them together there is a sense of security that we've been fighting for all season, said the United manager. We've had Jonny Evans out for long periods, we've had Wes Brown playing there as well as Ritchie de Laet, Michael Carrick and Darren Fletcher. When you see those two together, they've got the experience, authority and understanding with each other. It was great to see. That and with Edwin van der Sar coming back it makes an unbelievable difference. Any threat we had against us against Milan seemed to be snuffed out very early. That is an indication of the authority they bring to the team. I pray to the lord they stay fit until the end of the season. It definitely gives us a big chance because they bring us experience and consistency. What do you think? Have your say.
